I am a identical twin and 10 weeks pregnant and already have a large belly; could I have twins?

Mom Answers

OK here is the REAL answer. Identical twins happen by accident. Your being an identical twin will not influence your chances of having twins. Non-identical twins are the result of the release of more than one EGG, so it can only run on the mother's side of the family. If your mother, sister, etc have non-identical twins, your chance is somewhat increased, because you might also be a multi-ovulator. But no, if you are an identical twin, you have the same chance as everyone else of having identical or non-identical twins.

I am an Identical Twin, I miscarried identical twins (known because of shared placenta), and my family has 5 generations of identical twins with no skipping a generation. While it is supposidly not genetic, it appears it can be at times.

I was just reading about this as this is my fourth pregnancy I&#8217;m 10 weeks and showing much more than I did with my first three. I learned that although twins do run in families identical twins do not necessarily follow the same chances. Identical twins are created by the splitting of one embryo into two where twins are the result of multiple eggs during ovulation. The only &#8220;true&#8221; way to know is by ultrasound, although your Doctor can get an indication as to weather or not you could be carrying twins by the rate of growth of your uterus and by searching for multiple heartbeats by Doppler. For now breathe and ask your Doctor at your next visit, he or she should be able to tell you if you have merit for your concern by a quick examination.

The odds of having twins if you are a fraternal twin is higher than if you are an identical. From twin.com: The chances of having twins that are identical are approximately 1 in 250 or 0.4%. It is unknown as to why a fertilized egg splits to form identical twins. Identical twins do not run in families and there is no way to increase the probability of having them.
So If you are an identical it was a fluke by your egg and if you are having identicals it would be purley Coincidental.

That person who believes it's genetically impossible to have twins if you are a twin is simply mistaken - that idea is just ludicrous! Actually, being a twin increases your chances to have twins, because you are probably genetically predisposed to having twins. You also increase your chance to have twins slightly by taking pre-natal vitamins before conception.
However, it could also be that your due date was miscalculated, which is usually the cause of a larger-than-normal belly early in your pregnancy.

For all of you who are mentioning your baby's father and his father and so on and so forth, just an FYI. Twins are made by the female and the female only. It's either cause by the release of two eggs or one egg splitting in two after fertilization.

I have to disagree with the REAL answer. My great aunts are identical twins. both of them have a set of identical twins. The tendency for eggs to split has to come from somewhere. So it is possible to be having twins. You would be able to ask your doctor to do an ultrasound to find out.
